We just got in a Xi spring perch from the local dealer and it appears that the spring perch will work. I dont know why the other shop had a problem installing the perch but after comparing the Xi and the nonXi spring perches and the Lowering Perch I dont see an issue.

If one of you with an Xi wants to try these out we will give you the perches at no charge and even cover the shipping. I just need another person to try these out and let everyone know on the forum. We just dont have many Xi's locally or we would do you install for free as well. If you are in So Cal with an Xi get in touch with me.

Will these work on an 2008 335xi coupe? I am going to alex @ AK soon.. and I see your post above about trying these out... I don't know how much alex would charge, but these only go in the fronts? the xi is higher than the i regardless. I have the sports package with 17s on it.. I want to lower the car a bit, but because I have the xi.. I don't know if this will be enough. I am not looking for anything crazy, just to close the gap up. Shoot me a pm if you want, cause I have alex installing a bunch of stuff on my car in the next coming weeks I am going there.

I bought the front lowering perches from SupremePower and got them on to my OEM spring. The spring is compressed quite a bit but when I put it back oover the shocks and want to screw the perch and cover back on with the nut in the middle, my perch is sitting too high. I can't even get the nut on there...I can barely see the top of the part I'm supposed to screw it on. When I had unscrewed the nut in the first place, the OEM perch and cap sort of shot off. So I'm guessing somehow I need to force it down but not sure how. Anyone else run into this issue? Appreciate any ideas...Happy New Year!
